As many of you know, all instances of the Kontankt player share the Sustain pedal settings. This means that you set them ALL to normal sustain or legato mode, all instances will be set to only one operation.
Chuck Green figured out an easy workaround in Sonar. Simple use the default "legato operation" for all VST instances. When you want normal sustain pedal (such as a piano) simple open that instrument as a DXi plugin (rather than a VSTi). This will allow you to have instruments with both pedal operations.
